HAY-STACKER.

, Specification of Letters latent.

Application filed -December 30, 1910. Serial 110. 660,141.

To all whom it may concern:

Be it known that we, CLARENCE HEL- MICK and WILLIAM E. ADLER, citizens of the United States, residing at La Grande, in the county of Union and State of Oregon, have' invented certain new and useful Improve ments in Hay-Stackers; and we do hereby either side of the cradle, regardless of the exact position of the hay'on the cradle.

A further object is to provide a plurality of devices for, releasing the cradle, either of.

which may be used, depending upon the side upon which it is desired to dump the contents, and a still'further object is'to provide means whereby only one ofathereleasing devices may be operated at one time.

With these objects in view, the invention consists in the novel construction hereinaf-.

ter described and claimed.-

In the accompanying drawings forming a part of this application, Figure 1 is a view of the device in side elevation. Fig.2 is a. similar view with the cradle in its elevated position. Fig. 3 is a top plan view. Fig; 4. is a bottom plan view of the cradle, showing. the operating means. 'Fig. 5 is a rear eleva tion of the cradle. Fig. 6 is a view of the latter, partly invsection. Fig. 7 is a detail showing the manner of connecting the p ar-: allel arms with themeans for supporting,

the same.

In carrying out our invention, we provide a base portion 10 mounted on wheels 11, having a mast .12 extending upwardly from the base and braced-by means of members 13 connected with the base at the corners thereof. ,The mast carries two fixed collars or supporting devices 14 and 15, arranged to support rotatable collars l6 and 17, with which the devices carrying the cradle are connected by means of pins 18, 19, 20 and 21. A derrick arm 22 comprises a plurality. of members 23, 24, 25 and 26 connected at their forward ends with. the cradle and at the rear end of arm 22 a flexible device'27 is secured, such device extending thence around pulley 28 near the base of the mast and movable around the latter. On the under side of the derrick arm, bearing membersf29f and are secured and'acconimo-.

datewpins 20 and 21 secured to collar 17,

.The'icra'dle has also connected thereto a'plurality of arms 32 carrying bearing members 33 whereby the, said armsare. connected with collars 16, through the medium of pins and 19. i

, The construction above described permits the raisinglof the cradle and the swinging thereof to any desired position.

UNITED STATES PA NT FF CE Referring more particularly to the cradle it i which is an important feature of the {invention,. it may be stated: that the latter "consistsof lower side members 31, uprights 34 and 85rconne cted by cross pieces 36 and 87 and tie rods 38 and 39. Thedu'mping p0r-' tionincludes a substantially flat portion 40 having blades or prongs 41 projecting from" both'sides thereof. In order that the congardl'ess of the position oft-he cock with reference to thetransverse axis of the cra dle, wegprovide means for performing the dumping operation from both sides, and 'are bolts 43, 44, 45 and 46 are arranged to re-. ciprocate in apertures in side members .27 and 48' of member 40 to enterholes 49,

50, 51 and 52 in the. adjoining portions of- L tents may be 'dumpedin eitherdire'ction re-ff;

range forv l ocking a portion of the mecha fl nisr'n so that if both ropes connected with the operating lever are pulled at one time,.

by accident, no harm will -result. Locking 5 I the frame. A main lever 53 is. pivoted: at

54, and is held normally in'the position shown in'FigQ4 by means of springs 55 and. V .56, the. lever being operated by means of, f

ropes '57 and 58 passing around pulleys 59 and 60. Two short levers 61 and 62 are pivv oted on one side. of lever'53 and-are connect ed with the main leverby rods 63 and 64 secured-on opposite sides of the pivotal point 54, the short levers being also connected'by rods 65 and 66 with-locking bolts43' and 44. The'arm of the mainlever which connected at 67.by.rod 6 8iwith bolt 45 which .has connection as above with bolt 49 is also is in alinement with bolt 43,"and the other arm of lever 53 j has connection at 69 with bolt 46, by means of rod" 70. Bolt 46 is in alinement with bolt 44. .It will be observed:

that the pulling of either cord will cause.

one [set of bolts, oppositely located to be withdrawn from their lockedposition, thus no releasing that side of the dumping member,

while the boltsof the other set are carried] slightly farther into their locked position.

In order to provide for the returnof'the' dumping member to its locked position,

after being carried out of that position by the weight of the hay, the said member is connected with the framework at its upperportion by means of resilient devices 71 arranged as shown in Fig. 6, a retaining member 7 3 being disposed in line with'the transverse axis of the dumping member.

We do not desire to limit ourselves to the exact construction shown and described, but may make such changes as fall within the scope of the appended claims, without departing from the spirit of the invention.

.ofthe member,means for throwing the pivoted devices out of their operative position, on one side of sa1d axis, and a resilient devlcefor returmng them to their normal position.

2. In a hay stacker, a derrick arm and means for supporting the latter, a cradle frame'carried by the arm, a dumping member within the frame, a lever carried by said Copies of this patent'may be obtained for member, a plurality of locking bolts con nected with one arm of the lever, said bolts being in alinement and located on one side ofv the transverse axis of the dumping member, and a plurality of bolts connected with "the other arm of said lever and disposed on the opposite side of said axis, the bolts last mentioned being released simultaneously.

3. In a hay stacker, a derrick arm and means for supporting the latter, a cradle frame carried by the arm, a dumping member with the frame, a main lever carried by said member, a second lever opposite one arm of the main lever, a plurality of bolts connected with said arm, one of said bolts being directly connected and the other being connected through the medium of the second lever, and a plurality of bolts similarly connected with the other arm of the main lever, on the side of the transverse axis of the dumping member opposite to that on which the first set of bolts is located, the bolts connected with a given arm of the main lever being released simultaneously.

In testimony whereof we affix our signatures in presence of two witnesses.
